Don't call. Knock. Send one respectful attention request — they see it and tap I SAW IT. Private, end-to-end encrypted. No endless chat, no ringing. KNOCK is a calmer way to reach someone. Instead of calling and interrupting, or firing off a message that gets lost, you send a single KNOCK — a respectful request for attention. The other person sees it, and taps "I SAW IT" so you know they got it. That's it. No pressure to reply, no endless thread. HOW IT WORKS - Knock — send one attention request to a contact - Seen — you know the moment they've noticed it - I SAW IT — a one-tap acknowledgment, or a short reply if they want PRIVATE BY DESIGN - End-to-end encrypted. Your messages are encrypted on your device and can only be read by the person you sent them to — we never see them. - No phone number, no email, no real name required. - Face ID lock keeps the app private on your device. - Delete your account and all your data at any time, right from the app. BUILT FOR FOCUS - A knock arrives with its own gentle sound and appears right up front, so it stands out from the noise of a normal chat app. - Share your location with a single tap when you want someone to find you — and only then. - Block anyone, and turn off incoming knocks whenever you need quiet. KNOCK is for the people who matter — a partner, family, a close friend, a teammate. When you need their attention without taking over their day, you knock. Don't call. Knock.
